Having a second problem truly is a shame, gail. You've been one of the S100s champions, and until yours broke, I had hopes that mine might never fail. Now it appears I may be just waiting for the inevitable lens error.

Since LCD failure isn't common (at least to my knowledge) it does make me wonder if it is related to the lens repair.

I believe it is.

I'm still trying to determine whether I'm going to send the camera in for repair for the second time.

I've really lost confidence in my s100. I feel I have to carry a second camera as a back up, and that defeats the purpose of having a small camera. I will probably just carry my s90 now, a great camera though I prefer the s100; I mean I did until having all these problems.
